[issue41103] Removing old buffer support

[issue44609] Buffer support in the stable ABI
New submission from Tarun Johar : PEP 384 and PEP 652 define a stable ABI to be used with Python 3.2 and later. On Windows, symbols for the stable ABI are exported from the python3.dll shared library. The following functions are present in Python 3.9 but have been removed from Python 3.10b3: PyObject_AsCharBuffer() PyObject_AsReadBuffer() PyObject_AsWriteBuffer() PyObject_CheckReadBuffer() The justification for the removal of these functions was discussed in this issue: https://bugs.python.org/issue41103 Without these functions, an extension cannot utilize the stable ABI to access the buffer memory of data structures. The buffer protocol is suggested as an alternative, but the buffer functions PyObject_GetBuffer() and PyBuffer_Release() are not present in the stable ABI.

[issue43597] robotparser should support specifying SSL context
New submission from Tarun Chinmai Sekar :
IMO this could be enhanced by adding a sslcontext parameter to read method
a sample change would it could look like
```
def read(self, sslcontext=None):
"""Reads the robots.txt URL and feeds it to the parser."""
try:
if sslcontext:
f = urllib.request.urlopen(self.url, context=sslcontext)
else:
f = urllib.request.urlopen(self.url)
except urllib.error.HTTPError as err:
if err.code in (401, 403):
self.disallow_all = True
elif err.code >= 400 and err.code < 500:
self.allow_all = True
else:
raw = f.read()
self.parse(raw.decode("utf-8").splitlines())
```
Happy to send a PR if this proposal makes sense.

Re: Fwd: Unable to Install Python (3.5.0) Properly
Oh, My apology ! I should have mentioned the system stats in mail.

Later, it's asking for core.msi, dev.msi etc. Because system is not able to fetch from the web. The log file contains all these errors.

Python Query: Related to locking a resource in a multithreaded environment
Hello All, I've a configuration.ini file. This particular can be accessed by several threads of my application. Each thread can read/write configuration parameters from/to the configuration.ini file. I am using threading (Rlock) to lock the resource (configuration.ini file) while accessing it from any thread. I use the file available at http://www.voidspace.org.uk/python/configobj.html for read/write. I did the following in one of my files: import threading class Synchronization: def __init__(self): self.mutex = threading.RLock() Now this I can create instances of the class Synchronization and use acquire/release to work on the shared resource. But every thread would need to import this class and hence each thread would create a separate instance of the class. This means several lock variables. But I think we need a global lock flag that is accessible across all the threads. How do i do this? Please let me know ASAP.

Thanks a lot Robin. I tried using self.log and instead of self.log.list. *Code is attached.* But this gives me a panel and listctrl in it. The extra blank space around the listctrl in window1 is something that I don't need. Please help.

Creation of multiple threads
Hello All,
I got the following example from
*http://wiki.wxpython.org/LongRunningTasks*http://wiki.wxpython.org/LongRunningTasks
This example shows how a worker thread can be created from the main GUI and
the main GUI is notified when the worker thread has done its work..
But my requirement is:
I want to have two worker threads and each one notifies the main thread. It
could be possible that when a worker thread is running, other might be
tirggerd.
1) Can I do with only one Worker thread class?
2) Can there be only one notification function for multiple threads.

Re: Issue with wxPython GUI
Hi Laszlo Nagy, Thanks a lot. But the issue over here is that how will the child thread acknowledge the main thread that it has completed its task. For this I'll have to set some flag in the child thread and poll for it in the main thread. This will create a problem. Any alternatives??

The script has a many log messages, which it posts on some shared memory. The GUI reads the messages from the shared memory, in the Idle loop. But the script is huge and so the logging is not run-time. Rather this happens only after the script has executed. Moreover, the GUI becomes un-responsive till the script has completely executed. This is (probably) because you are running your script in your main thread. While the main thread of the application is running, your windowing system cannot process message queues. Since the updating of a text control uses window messages, it has no chance to process them. I recommend that you run your script in a separate (terminateable?) thread, send your messages into a Queue instance, and load messages from that queue in your main thread. Do you have any suggestions for this? Well, if you do not want to create more threads, it migth work if you call this periodically from your main thread (but I did not try this): wxApp::Dispatch *virtual void* *Dispatch*() Dispatches the next event in the windowing system event queue. This can be used for programming event loops, e.g. while (app.Pending()) Dispatch(); -- http://mail.python.org/mailman/listinfo/python-list

What kind of problem, can you explain? Supposing your child (worker)
thread created the output, I would do it this way (untested):
class Child(threading.Thread):
def __init__(self,output):
self.stop_requested = threading.Event()
self.stopped = threading.Event()
self.output = output
def run(self):
try:
while not self.stop_requested.isSet():
# put your algorithm here
# but check periodically if you need to abort the job.
if self.stop_requested.isSet():
break
...
# when you have data, put into the output queue
Issue with wxPython GUI
Hi All, I've a probelm and solution for it to build the preface. Below it is the new problem I'm facing. Can someone help me out? *Problem:* I've have created a GUI (using wxPython widgets) where in I've a message log window (A TextCtrl window). I've a router.dll that helps me putting in message onto a channel. In my script that generates the GUI, I want to continuously poll the channel and populate the messages from the channel to the message log window. For this I've to put a while (1) loop, but when I do this, the GUI doesn't come up. I see the GUI coming when while(1) is removed. Is there any issue with usage of app.mainloop and while(1) together. *Solution: *I used: self.Bind (wx. EVT_IDLE, self.OnIdle) And in the OnIdle function, I check if the data is available on the channel. Referred: http://wiki.wxpython.org/LongRunningTasks *New Problem: *I am opening and executing a script from the GUI. The script has a many log messages, which it posts on some shared memory.
